CONCRETE FENCE CONSTRUCTION.

Specification of Letters latent. Patented A11 10, 1915.

Application filed October 2, 1914. Serial N 0. 864,550.

To all/whom it may concern -Be it known that I, Gnonen AUER, a citizenof the United States, residing at lVhite Plains, in the county of\Vestchester and State of New York, have invented certain new and usefulImprovements in Concrete Fence Construction, of which the following is aspecification.

My invention relates to the construction of reinforced concrete fences,serviceable especially as guard rails along country highways and also inother places.

The object is to enable the production of a strong, durable andeconomical fence from separately formed sections, which are asse mbledin a novel manner, as will hereinafter be more particularly set forth.The fence, while made of previously formed units, is as strong asamonolithic struc ture and possesses special advantages in erection andmay also be taken down without substantial injury.

In the accompanying drawingsillustrating two embodiments of theinvention: Figure 1 is a side elevation of a portion of a fenceembodying my invention; Fig. 2 is a fragmentary sectional elevationshowing the meeting ends of two top rail sections tied to the top of oneof the posts preparatory to the completion of the joint; Fig. 3 is asimilar view showing the-joint completed; Fig. 4.- is a centraltransverse section through Fig. 3; Fig. 5 is a horizontal section on theline 5-5 of Fig. 4; Fig. 6 is a view similar to Fig. 2, showing anotherembodiment of the invention; Fig. 7 is a View, partly in. section andpartly in elevation,

' showing the joint of Fig. 6 completed; Fig.

8 is a central transverse section through Fig. -7 and Fig. 9 is-ahorizontal section on the line 99 of Fig. 8.

The posts 1 are cast separately in suitable molds, either on the job orelsewhere,

' though usually it is more convenient and less expensive tomold themand the other sections at the place where the fence is to be erected. Inthe sides of the posts as molded are sockets 2, and reinforcing rods 3and 4. are embedded in the posts and extend throughout the lengththereof. The number and arrangement of these reinforcements maybevaried, but, as shown, there are five, one adjacent each corner and one1n the middle In accordance with the invention, one or more embeddedmembers project from the top of each post for engagement with e'mbeddedmembers in the top riiil sections. In the particular instance shown,there is one pro ecting member for each post, the same being the middlereinforcement 4, which is extended above the post while the othersterminate at or below the upper end thereof; but manifestly the precisedetails may be varied.

The top rail consists of separately formed sections 5 or 5 which extendapproximately from center to center of the posts, their ends beingsupported substantially in abuttlng relation on the tops thereof. Thesaid sections, like the posts, are cast in appropriate molds, whereinthey are given the ornamental formation shown, or such other shape asmay be desired. These sections have' members embedded therein to engagethe projecting post members i, in order to tie the rail sections to eachother and to the posts; and in both forms-of the invention shown, theengaging portions of the said members, after the parts are in place, arecovered by bodies of concrete which is poured in liquid or plasticcondition into recesses in the meeting ends of the rail sections,thereby both protecting the metal members and forming a key oradditional union between the parts.

Reference will now be made more particu- .rail sections have three orother suitable number of longitudinal reinforcing rods 6 embeddedtherein at the time the sections are made, the same extending throughoutthe length of the sections and one or more of them having projectingeyes 7 at their opposite ends. The said rods are preferably slightlyoifset at their ends, near the eyes, so that the latter are brought intosuperposed relation when the sections are assembled'end to end, as willbe clear from Fig. 2. The projecting ends of the rods 4: are receivedwithin and extend above these eyes, and are threaded as indicated at 8in order that nuts 9 may be screwed down upon the eyes, in order toincrease the strength and security of the constructim.

The rail sections as molded are formed with complementary recesses 10 intheir ends, which when the sections are assembled form cavitiesextending downward from the top of the'rail to the eyes, the saidcavities being of suflieient size to accommodate the nuts and a Wrenchfor applying "the same. After the parts are in position and the nuts 9have been applied, the cavities are filled with fiuid concrete, whichhardens and forms the keys 11.

In the construction shown in Figs. 6 to 9, the top rail sections 5 areprovided with three reinforcing rods 6; and, in addition, tie plates ormembers 12 are embedded 1n the adjacent ends of the sections after thelatter are in pliice. To this end the said sections have recesses 10formed in their ends in the molding operation, these recesses extendingfrom the top downward for. a suitable distance and for a substantialdistance lengthwise of the rail sections, so that when the latter arepositioned end to end a slotlike cavity is produced at each junction.Below this cavity the end faces are channeled to accommodate the rods4:. Into the slot-like cavities are placed the plates 12, havingopenings intermediate their ends through which the said 'rods project,to be engaged by nuts 9 as before. When 'the parts are thus assembledthe cavities are filled with fluid concrete forming the bod cs 11, whichare finished off to conform to the contour of the rail sections and forman integral union between the same, in addition. to the mechanicalconnections afforded by the embedded members.

The fence is completed by intermediate rail sections 14, separatelymolded like the others and containing suitable reinforcing elements.These rail sections are inserted at their ends into the sockets 2 in theposts.

My fence, in contradistinction to most, if not all, prior concretefences of an integral character, may be readily taken down and put upagain. All that is necessary is to break out the cast-i "keys ofconcrete and disengage the tying means from the projecting post members.The fence is set up again in the manner already described and plasticmaterial again filled into the pockets at the adjoining ends of the toprail sections.

What I claim as new is:

1. A reinforced concrete fence, comprising, reinforced concrete posts,said posts having members embedded therein as formed and projecting atthe'tops of the posts, a reinforced concrete top rail formed separatelyfrom the posts and in sections. the adjoining ends of which rest on topof the posts. said sections being provided as formed with recesses attheir adjoining ends forming pockets open at the top over the posts,means for tying the rail sections to caih other and to the posts, saidmeans ens ae'ing said projecting post members within said pockets, andkeys of concrete cast into said pockets and embedding the engagingportions of the tying means and post members.

2. A reinforced concrete fence, compris at their adjoining ends formingpockets open at the top over the posts, means for tying the railsections to each other and to the posts, said means having openings receiving the ends of said rods within said pockets, nuts screwed onto therod ends above the tying means, and concrete cast into said pockets andembedding the rod ,ends with their nuts and the engaging tying means. i

3. A reinforced concrete fence, comprising reinforced concrete posts,said posts having members embedded therein as formed and projecting atthe tops of the posts, a reinforced concrete top rail formed separatelyfrom the. posts and in sections, the adjoining ends of which rest on topof the posts, said sections being provided as formed with recesses attheir adjoining ends forming pockets open at the top over the posts, atie member in each of said pockets partly within each of the twoadjoining ends of rail sections and fastened intermediate its ends tothe corresponding projecting post member, and keys of concrete cast intosaid pockets covering the tie members and post members.

4. In a reinforced concrete fence, reinforced concrete posts havingmembers embedded therein and projecting at the tops of the posts,incombination with a reinforced concrete top rail separately formed andcomprising. sections having their adjacent ends supported on top of theposts, keys of concrete cast into recesses in the adjacent ends of therail sections, and tie plates disposed in these filled recesses andcovered by the concrete keys, said plates having openings intermediatetheir ends engaging the projecting portions of the members embedded inthe posts.

5. In a reinforced concrete fence, reinforced ooncrete posts havingmembers embedded therein and projecting at the tops of the posts, incombination with a reinforced concrete top rail separately formed andcomprising sections having their adja cent ends supported on top of theposts, keys of concrete cast into recesses in the adjacent ends of therail sections, tie plates disposed in these filled recesses and coveredby the concrete keys, said plates having openings intermediate theirends engaging the projecting portions of the members embedded in theposts, and retaining devices on said post members above said plates andalso embedded in said filled recesses.

6. A reinforced concrete fence, comprising relnforcedconcrete postshavlng members embedded therein as formed and prosections being receivedin said sockets, a reinforced concrete top rail formed separately fromthe posts and in sections, the adjoining ends of Which rest on top ofthe posts, said sections being provided as formed with recesses at theiradjoining ends forming Copies 0'! this patent may be obtained for fivecents eaeh,by addressing the Commissioner of laten ts.
